This invention relates to a ventilating apparatus for toilet bowls andparticularly to a mechanism for controlling the operation of saidapparatus.

The object of the invention is to provide a toilet bowl with aventilating apparatus so associated therewith that if said bowlbecomesclogged and the water therein rises above its usual level whenthe bowl is flushed 10 that said water will not interfere with'orsubmerge said apparatus.

Another object of the invention is to provide a novel mechanism foroperating a switch' that controls-the operation of the electric motorwhich drives the suction pump, said mechanism operating automatically toclose the electric circuit to said motor when the seat is depressed, andalso to open said circuit when pressure upon said The invention consistsin a ventilating a paratus for toilet bowls asset forth in t e followingspecification and partichlarly as pointed out in the claims thereof.

Referring tothe drawings':--

Figure 1 is a side elevation of a toilet bowl, a ventilating apparatusembodying my invfintion beingillustrated-associated therewit 30 Fig. 2is a. plan view of a portion of the apparatus illustrated in Fig. 1, aportion of the cover for the toilet bowl being broken away to moreclearly illustrate partslocated .therebeneath. 4 7 Fig. 8 is a detailvertical section taken on the line 33 of Fig. 2, the cover for thebowlbeing raised and the seat being illus. t'rated in its depressedposition.

Like numerals. refer to like parts throughout the several view's'ofjthedrawings. In thedrawin'gs, 5 represents a'toilet bowl of well-knownform, 6 a seat, and 7 a cover located above said seat. The seat 6has acushion 8 attached to the undersurface therea of and so positionedrelatively to the top edge of said bowl that when said seat is depressedsaid'cushion will tightly close any space that there may be between saidseat and said bowl.

0 Rigidly fastened to the top surface of the bowl 5. adjacent to therear'thereof, are a pairof similar brackets 9 in which. a rod 10 ismounted, and the latter constitutes a pivot for the cover 7-which is.connected. to said v 5 rod by a pair of arms 11. p The cover 7 has whichare 7 15. The r0d15, therefore, constitutes a pivot 'nozzle is connectedb V its.undersurface at the front thereof, and said cushion rests uponthe front portion of the seat '6.- Pivotally mounted upon the rod10vbetween the arms- 11 of the cover 7 is a rocker member 13, and thelatter has a-pair of forwardly projecting arms 14 formed integraltherewith in which the rod 15 is mounted. 1

A plate 16 is secured to the undersurface of the seat 6 adjacent totherear thereof, and said plate has a pair of rearwardly projecting arms 17formed integral therewith. pivotally mounted upon the rod a cushion 12secured to for the seat 6 and in its normal position said seatat therear-thereof is raised, so that its cushion 8 is outof engagement, withthe top edge of the bowl 5, except at the very front of said bowl.,A-forked member 18 is connected to the opposite extremity of the rocker13 from that to which the seat 6 is pivoted, and said forkedmember isconnected by a weighted connecting rod 19 to a switch 20 hereinafter tobe more fully described. The connecting rod 19 constitutes a weight andis sufliciently heavy to normally hold the seat 6 in the raised positionillustrated in Fig. 1.

Resting upon the upper surface of the toilet bowl 5 at the rear thereof,with its" entrance positioned adjacent to the rear'of the seat 6, is asuction a vent pipe 22 with a suction pump 23 drlven by an electricmotor 24. A discharge. pipe 25 leads from the nozzle 21, and saidsuction pump 23 to. any suitable location,

but preferably said pipe discharges into the open air.

The switch mechanism 20, previously mentioned, embodies therein a pairof electric contact m'embers'26 and 27',- both of which are mountedupon-an insulating block 28 mounted within a casing 29. The contactmember 26 is connected by a wire 30 with the electric motor 24. Thecontact member 27 is connected by a wire 31 with a suitable source ofelectric supply 32 and the latter is i connected by a wire 33 with themotor 24. The weighted connecting rod. 19 is operatively connected witha lever 34 pivotal'ly mounted at 35- within 'the casing 29,,and

said lever has a push member 36 constructed i of insulatingmaterialfas't thereto and adapted to engage the contact member;26 whensaid lever is rocked, thereby forc ng .10, thereby operating normalposition said contact member into engagement with the contact member27,. and completing the electric circuit through said members- Wheneverthe seat 6 is depressed, which happens whenever a person is seatedthereon, the member 13 is rocked upon its pivot the lever 34 to completethe electric circuit at the switch 20 to the motor 24, and the immediateoperation of the suction pump 23 causes the suction created to dischargethe fumes from the toilet bowl. I

As soon as the pressure upon the seat 6 is removed, the weighted member19 will immediately cause the seat 6 to return to its as illustrated inFig. 1, at which time the electric circuit at the switch I 20 will bebroken.

. rigidly connecting said seat The cover 7 is so mounted'upon the pivot10 and rests in such a manner upon the front of the seat 6 that anypressure downwardly thereon, as by a person sitting upon said cover,will not the seat 6 other than to slightly compress the cushion 8 at thefront of said seat.

It is evident that all of the mechanism hereinbefore described is soarranged with relation to the toilet bowl that if the latter in any waybecomes clogged, so that in flushing the toilet the water therein risesabove its accustomed level, that none of the parts of this mechanismwill be submerged.

It is furthermore evident that'as there is no switch or electric wireseither upon the seat or adjacent to the top of the toilet bowl thatthere will be no danger in the device of this invention of watersplashing within the bowl causing short circuits in the electric switchor wires connecting thereto.

I claim 2- 1. In combination a toilet bowl, a vent pipe communicatingtherewith, a suction pump connected to said pipe, an electric motor forsaid pump, a switch for said motor, a seat for said bowl, and a weightand said switch, whereby the latter is operated by said seat to controlthe operation of said motor.

have any effect upon 2. In combination a toilet bowl, a vent pipecommunicating therewith, a suction p connected to said pipe, an electricmotor for said pum a switch for said motor, a seat for sai bowl, andmeans operatively connecting said seat with said switch, whereby thelatter is operated in unison with said seat to control the operation ofsaid motor, said means embodying therein a weight comprising a rigidconnecting member and adapted to hold said seat in its normal position.

3. In combination, a toilet bowl, a vent pipe communicating therewith, asuction pump connected to said pipe, an electric motor for said pump, aswitch for said motor, a rocker pivotally mounted upon said bowl, a seatfor said bowl pivotally attached to said rocker, and a weight connectedto said rocker and adapted to hold said seat in a raised position, saidweight also being operatively connected to said switch, and comprising;a rigid connection between said rocker and switch, whereby the latter isoperated in unison with said seat to control the operation of saidmotor.

4. In combination, a toilet bowl, a vent pipe communicating therewith, asu'etion pump connected to said pipe, an electric motor for said pump, aswitch for said motor, a pair of brackets mounted upon said bowl, apivot member in said brackets, a

rocker mounted upon said pivot members, a seat for said bowl pivotallyattached to said rocker, a weight connected to said rocker and adaptedto hold said seat in a raised position, said weight also being'operatively connected to said switch and comprising a rigid connectionbetween said rockerand switch, whereby the latter is operated in unisonwith said seat to control the operation of said motor, and a cover forsaid bowl also pivotally mounted upon said pivot members.

In testimony whereof I have hereunto set my hand.
